When I got it, the slide stop was modified to not lock back at empty. I installed new stop and it would only lock back with certain mags. Installed longer 170mm mag springs and the slide locks back on all mags but sometimes will drop when I eject the mag. Slide lockback with certain mags problem free but other mags it will sometimes not push the stop up enough and slide will drop sometimes but not always.
You paid for SV. You get factory support, call the shop. Sounds like you might be messing with sucess, is the gun broken in?
You are correct, most LIM/OPEN shooters do not want the gun to lock back.
Unfortunately, I bought it used...does the warranty cover second owner?
I often get heat about my choice for lockback. The main reason is that our multi-gun match rules require ditching pistol with slide locked back and I feel it's quicker to shoot an extra shot or two to dry than to eject and manually lock the slide back. Additionally, I shoot L10 and can't seem to count to ten under the pressure of the COF.
Call Brandon at 972-513-1911 to see if he can help you with your pistol. If it is a factory built pistol, he may be able to help you out. Personally, I would put the original slide stop back in along with Grams guts in the mags and get used to locking the slide manually.
Thanks! I will give him a call. Is he with Strayer Voigt?
Yes Brandon is with SV & his last name just happens to be Strayer.
